My dad gave me a second-hand Nissan mid-size Frontier and I need to change the tires since it's a little worn out.
Is Mickey Thompson tires a good choice for this? I found a good deal from 4WheelOnline.

The rule I've always worked by is 'pay a lot of money for the things that keep you connected to the ground', ie tires, mattresses, and shoes. tires are something i don't skimp out on, especially since they're one of the biggest factors in your car's safety. consider spending more if you can.

edit; i just checked some reviews, mickey thompson seems to be pretty alright.
